NAME

cexp, cexpf, cexpl - complex exponential function

LIBRARY

Math library (libm, -lm)

SYNOPSIS

bash

#include <complex.h>

bash

double complex cexp(double complex \nz\n);\n
\nfloat complex cexpf(float complex \nz\n);\n
\nlong double complex cexpl(long double complex \nz\n);

DESCRIPTION

These functions calculate e (2.71828..., the base of natural logarithms) raised to the power of z.

One has:

bash

cexp(I * z) = ccos(z) + I * csin(z)
